the whole idea of a "castle" is stupid if you want to stay safe a bunker preferably underground would be much smarter...and that "castle" has tons of huge windows to throw grenades INTO... and as was stated that downstairs door is a joke, i would give that family and "castle" a 2 month initiate survival time... the idea is to blend in not yell out hey look at me i have a castle and a bunch of spoiled kids and a douche bag son lol...
